Wolf’s Lair, Poland
The abandoned bunker in Ketrzyn, Poland, holds disturbing memories of the Nazi regime. The Wolf’s Lair was one of Adolf Hitler’s headquarters and hideouts during WWII. It is now covered in moss and plants from the surrounding Polish forest.
The Wolf’s Lair is most well known for Operation Valkyrie – An assassination attempt on Hitler where one of his colonels detonated a bomb inside of the headquarters. Miraculously, Hitler survived the blast with few injuries.
